Initiatives that humidify using plants, etc, and soak up carbon dioxide should be encouraged. An Arab-Korean initiative intends to build an agricultural city in the barren Qattara Depression. Extensive use of greenhouses is to be implemented and if done throughout Africa this could help. ​ https://www.arabfinance.com/en/news/details/egypt-economy/407484 explains. Another concept that will probably come to the fore is the use of moist air to enable plants to grow. Recently plant physiologists have shown that absorption of water from leaves and transport of this water to roots occurs. The concept of moist air from greenhouses supplying water to plants via leaves could be a future reality.
